Water potential of protoplasm of the cell is equal but opposite in sign to the diffusion pressure deficit(DPD) or suction pressure(SP).Thus DPD of an osmotic system is the water potential in terms of energy.DPD is expressed in positive value.

How does the pressure of affect the rate of diffusion?
The higher the pressure, the more easily a chemical diffuses. And seeing as pressure and temperature are directly related, the higher the temperature the more easily a chemical diffuses, and vice versa. This is caused by everything "wanting" to be equal, if there is a higher pressure, then it will diffuse to an area of lower pressure.
What drives Facilitated diffusion?
Facilitated diffusion is a passive process whereby a molecule is "carried" across a semi-permeable membrane by a channel or protein carrier. Like diffusion, this process requires no energy, however, since passive diffusion can drive movement against a concentration gradient it is not really diffusion.
Oxygen crosses the plasma membrane by?
Simple diffusion process, i.e. from high pressure to low pressure
If diffusion is going to occur there has to be what?
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
Molecules move in and out freely from high to low concentration?
Due to diffusion pressure gradient through the cell wall
What is the difference between waterpotential and diffusion pressure deficit?
Water potentialrefersto the power of to move from oneregionto another region where as DPD is thesuction ability of a cell or solution separated by semipermeable membrane.
Is osmosis diffusion through water?
yes osmosis is diffusion through water diffusion is a random movement of molecules from a high area of pressure to a low area of pressure
As partial pressure increases what happens to the rate of diffusion?
Rate of diffusion will increase.
What is driven by hydrostatic fluid pressure?
Diffusion, Osmosis
What is the different between turgor pressure and diffusion?
The difference of turgor pressure and diffusion is that turgor pressure is an osmotic pressure exerted by the contents of a plant cell against its cell wall; while diffusion is a movement of molecules from an area higher concentration to an area lower concentration.
Can you make a sentence with Budget deficit?
The government was under pressure to raise more taxes due to the budget deficit they had.
Where within the body does pressure affect diffusion of a substance?
Pressure increases the rate of diffusion. As the pressure on the membrane increase, attempts to enter the lower concentration increase, speeding the diffusion rate.
IS The movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called diffusion?
No, diffusion deals with concentrations not pressures.
The movement of fluid through the cell membrane from a high pressure area to a lower pressure area is called?
active transport
Can you use deficit spending in a sentence?
President Obama faces strong political pressure to curb deficit spending in the United States.
What is it called when its high pressure to low pressure?
Actually, atoms in higher pressure regions disperse to lower pressure regions. This is diffusion.
What will be zero in a fully turgid cell?
Diffuson pressure deficit wiil be zero
